Emmedue Building Small

Emmedue panel construction is a great way to build an energy efficient, and seismic resistant home. Here in the USA, Emmedue is commonly referred to as M2 Panel construction.

The M2 Construction System uses wall and roof panels that are clipped together and sprayed with concrete. Once the concrete is applied, the structure is strong in 3 dimensions and can resist earthquakes, hurricanes and fires.

Emmedue- M2 panels are now being produced in the USA at a plant in Mississippi. We have featured an innovative M2 home being built in Texas. The owner, Hubert has been sharing construction photos and videos of the progress.

Hubert’s formula for the exterior stucco his Emmedue house is:
